Revision 1.2, Sun Jul 30 05:51:16 2023 UTC (7 months ago) by mrg
Branch: MAIN
Changes since 1.1: +0 -0 lines

initial merge of GCC 12.3.0.

this doesn't include any of the changes to the .c -> .cc files renamed,
and reverts our local changes to the vax port and libsanitizer subdir.
vax GCC was rewritten and our local fixes no longer are relevant, and
the new libsanitizer is more updated than our old one, and merging via
gcc10->gcc12 is not really possible.

unfortunately, our local changes to libsanitizer that aren't related
to the general update of those sources (ie, the netbsd code) will need
to be re-checked and perhaps re-ported.

On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects
conformance to the procedure call standard (AAPCS) has been fixed.

Many optimiser improvements

DWARF-5 support.

Many new and enhanced warnings.

Warnings about format strings now underline the pertinent part of
the string, and can offer suggested fixes.

Several new warnings related to buffer overflows and buffer

New __builtin_add_overflow_p, __builtin_sub_overflow_p,
__builtin_mul_overflow_p built-ins added that test for overflow.

showing the source lines that correspond to the assembly.

The gcc and g++ driver programs will now provide suggestions for
misspelled arguments to command-line options.

AArch64 specific:

import GCC 5.3.0.  see these urls for details which are too large to
include here:

(note that GCC 5.x is a release stream like GCC 4.9.x, 4.8.x, etc.)

the main issues we will have are:

The default mode for C is now -std=gnu11 instead of -std=gnu89.

The deprecated option -mwords-little-endian has been removed.
The options -mapcs, -mapcs-frame, -mtpcs-frame and -mtpcs-leaf-frame
 which are only applicable to the old ABI have been deprecated.

The o32 ABI has been modified and extended. The o32 64-bit
 floating-point register support is now obsolete and has been removed.
 It has been replaced by three ABI extensions FPXX, FP64A, and FP64.
 The meaning of the -mfp64 command-line option has changed. It is now
 used to enable the FP64A and FP64 ABI extensions.
